The Hotech 2" is a marvel of accuracy and ease of use. I verified it was collimated, then collimated the scope in about five minutes.  Pricey but it costs a lot less than many eyepieces touted on these very boards.

After setting everything I removed the Hotech, rotated it 180 and rechecked... spot on. did this test several times. My focuser is precise, that may be why it works so well.

If you get a bad one send it back.

I thought the best for the money was a star?

Lots of ways to collimate. The person's skill level is the most variable factor that I've seen. Lots of bad secondaries out there too. The sight tube/cheshire combo puts it all together correctly.

 

Here's the DIY el cheapo method: You can make a sight tube from 1-1/4 inch sink tailpiece from Home Depot or Lowe's. Use an old 35mm film canister top with a hole centered in it for a collimation cap, especially if you line the underside with white reflective material. You can even get some nylon thread and make cross-hairs for the tube if you want.

 

Me? I have a Ho-Tech, cheshire, sight tube, dedicated barlow, and collimation caps. I'm picky about collimation... Just not rich enough for the Glatter... yet. BTW, I gave my Orion laser away a long time ago.
