lI have the the Andrews 2" 30mm 80 deg - it performed poorly in my 6" dob (I imagine it would be even worse in my 10" -haven't tried my 10" with it yet- as the 6" dob is supposedly more forgiving on ep quality compared to 10"). Great for surfing the skies, but don't expect quality. Stars aren't pin point and hugely lacks in contrast (the sky was never black for me, compared to all my other eps). The glass itself has got a green tinge. I ended up using the cheap 25mm that came with the scope more, and even my Orion Expanse 15mm (66 deg i think) was a massive improvement. It is cheap for a 2", and if you're driven by price, what you pay for is what you get with this ep in my opinion. Here is a link to a review (tho on the 80 deg).

The equivalent I think would be William Optics. A 2" William Optics 72deg SWA sells for around $185. Or a 1 1/2" for $104.95 from Ozscopes .

I think W.Optics would be a step up, I've read good reviews on it, and Liz here has the SWA and she loves it. Personally, I prefer around 70deg, as I find it just too much work and loss of light with 80deg. Once you start talking 2", you start talking lots of dollars as no doubt you are finding out. But if you don't want to critique them too much and driven by budget, that's a different story.
Just my experience and opinion.
