I personally like Mooers. I think of all the Asian clone companies, they are the best. I have a Blues Crab (Bluesbreaker), Flex Boost (AC booster), Hustle Drive (OCD), and the Trellicopter (Demeter Tremulator). I love all of them for different things. I'm planning on getting the Ana Echo (DM-2) and maybe the Green Mile (Tubescreamer). I've heard bad things about the other delay pedals and the reverb pedal.
I'm also planning on getting a Mooer Mod Factory to do pretty much exactly what you are talking about. I don't have much call for a UniVibe or phaser or flanger, but every once in a while, I do need one of them; which makes the Mod Factory perfect. At $88 bucks it's not hard on the wallet, and with the small foot print, it doesn't take much pedal board real estate.
