I like that the Skywatcher 150p comes with a 2" focuser, but would prefer to upgrade from rack and pinion. Anyone know of any focuser upgrades that require no modifications?

Do you have a Skywatcher 150P?  There maybe some but my gut feeling based on what I know is that there isn't.  If you have one and take a photo of the focuser, it's possible that the focuser and base are separate and that a Skywatcher or Orion Crayford body would fit.  You can also clean and adjust the stock focuser and improve it significantly.

 

If you don't have one yet, the 8 inch Apertura at $469 from high point scientific might be a better choise as when you add a two speed focuser upgrade to the 150P your probably pretty close to the Apertura.

Did you mean you would like to upgrade to a rack and pinion?  The 150P comes with a 2" Crayford focuser.

Unless the information on the website is outdated, it says the 150P comes with a rack and pinion. Highpoint Scientific also lists it as having a rack and pinion.

The Apertura AD8 was my first idea, but it's a bit out of my budget. I've been trying to decide between the XT6 and the Skyline 6 from Orion. The Skyline is only $50 more than the XT6 but comes with a Crayford focuser and 2 eyepieces. The AD8 is $150 more than the Skyline and I just don't know if I want to swing that much. I figure if I really get into it I'll grab an AD10 or AD12 in the future. I had also thought maybe the Zhumell Z130 tabletop, but then I would have to get a table or stool to set it on, or buy a tripod since it has a dovetail mount and tube rings. I've also heard the Zhumell won't be as forgiving with collimation since its a faster scope at f/5, where the Orion 6" scopes are f/8. I figure even if I save a bit with the Z130 I'll just end up putting it into a tripod or table, collimation tools, and end up spending as much as I would for a 6" full size dob that doesn't need a table and is a little more forgiving if all I have is a collimation cap at first.

Some CNers have replaced the 1.25in/2in adapter on the SW and otas with a low profile singlespeed with a helical insert for fine focus.

 

You may try this Svbony 1.25in micro focuser with 2in adapter. Available on Amazon and ebay also. ~40usd or less.

If it suits your needs, it will save you the cost of a new focuser.

 

Good viewing,
