GOTO equatorial mount that also acts as NON-goto?

Most nights I just want to lug the telescope setup to the driveway, point the RA axis roughly towards the north, turn on the power, point the telescope manually at a planet (or sun) and do some casual viewing. The problem is, the two GOTO mounts I've owned (Celestron AS-GT and one of the Orion mounts) don't let me do that. They just sit perfectly still until I do a star alignment.

Both my Meade LX200-classic and my Celestron CGE do this.
I havent tried it on the CGE.. Is that at turn on before star-align?

just 2 or 3 button pushes on the hand control.
Yes, the SynScan controller (what Orion scopes use) provides that capability as well, though it's probably more than just a few button presses to get to the right option in the menus. It would be nice if they just started up running like that but doing the button presses is not too much extra hassle, really.

The beauty of this kind of mount is that it can run for hours and hours off of a very small battery pack. Since the motor is only ticking away, and you aren't powering a computer and doing a lot of slewing, you only need 100 milliamps or so of power to tick the stepper motor over. pack made from 1200ma AAA batteries will run the mount all night!
If you do want to locate objects, you can turn on the Sky Comander and knock off a quick alignment.
The Sky Commander system allows you to move the mount manually at any time an works independently of the RA motor, and you don't loose your pointing (the way you do if you unlock the axis of most Go-to Mounts and move the tube manually). Push to mode can actually be much faster than Go-to, and it is essentially silent. Even the best Go-To mounts make some noise when slewing.
I owned a GM8 with Sky Commander and sometimes I miss it. They are lovely little mounts with decent carry capacity.
My biggest complaint was that there was a lot of clutter with the way the Digital Setting Circles were added to the mount.
Still, it is a really beautiful mount, and if you want the option of running for many hours off of a compact battery pack, but also haveing the ability to turn on the DSCs and Push To, it is a great option.
I also had a Ci-700 with DSCs. I regret selling that one too. For my 6" APO, I often spend time just cruising around, Dob Style, but the CI-700 could always keep up with the pistion. With the Meade LXD 750, I have to slew. It is a fast mount though, but now I am locked into a big battery or power adapters and AC power or something.
Sometimes, simple is better. I wish I still had those two mounts. I like my CG5 ASGT, and I like my Meade LXD-650, but the GM8 and the Ci-700 have their merits too.

Have couple Argo's (one on a Dob another on a WO EZ Touch) that work well too.

I stupidly sold the mount to buy an Atlas Go-To after all the initial talk about the Atlas being a competitor to the G11. I was way disappointed by its stability. I badly missed the C1-700 then.
When I got the big 6" f/8 Astro Physics refractor, I was looking for another Ci-700 but the LXD-750 came along. Would trade my Meade LXD 750 for one in a second.
I have to say though that he Meade LXD-750 is a more stable mount and I actually LIKE the handset function. It was surprisnly good software considering it was one of the first Go-To mounts on the market.
But back to the OPs point, I LIKED the push-to. It ran from a small battery all night, and was quiet, and I could push to faster than I could Go-to.
If anyone out there has a Ci-700 with DSCs and wants to trade for a LXD-750, let me know! LOL.
