My buddy and I play in bars around New Jersey. We rented equiptment last summer, now we need to buy because we'll be having 3-4 gigs a week. I was hoping everyone could enlighten me on some deals, shortcuts, things to buy, things NOT to buy. Any help would be greatly appreciated.

Here's what we need:

2 Microphones w/ cords
1 Mixer...we don't really need more than maybe 5 or 6 channels.
2 Speakers...15's?
Speaker stands and cables

Thanks so much
