We are getting ready to start perfoming--coffee houses and the like, and I need advice from folks who are not trying to sell me stuff! I saw what looked like a great amp on ebay, but I like to be an informed consumer so I didn't bid. It was a Crate Acoustic--CA125. Sold for $380. Did I blow it?

Here's what I think we need--2 mics for singing, a pic up or separate mic for a 12 string accoustic guitar, mic stands, mic cords, amps (or preferably one amp that has 3 plug ins, to reduce storage space and floor space and car space, and wear and tear:-) on our backs). Where should we start? What are some brands to avoid or look for ? Am I just asking impossible questions?
