dilema while collecting parts for the 10" dob i'm putting together.

I figure [no pun intended] that on down the road somewhere it's likely i may decide to make a mirror [apparently about the only way to get a really good one w/o spending an astronomical amount of $$] but right now i don't begin to have the time or place to do it so i was looking for a usable mirror at a reasonable price just to be able to get the scope 'up and running', so to speak.

I imagine any 'bargain' parabolic mirror will be of a 'mass produced' [if that actually is possible because of the 'nature' of the curve involved? i think they probably take a spherical mirror and do a minimal amount of additional figuring (either manually or by a machine?) so it isn't quite spherical anymore?] chinese variety that probably aren't all that hot but at the same time probably 'work' to one degree or another.

I was considering an 'ebay' mirror but found out that hands-on optics carries some very reasonably priced primaries and picked one up through them for about the same price i could have got one on auction [and this way if it turns out to be a real dog i may have some recourse since i've heard good things about this company's customer service]. You just may want to consider doing the same if you're in the market for an inexpensive primary to 'get the ball rolling'.
