sennheiser e604 3pk. 300.00, super nice for the cash. as far as overheads go, there are alot of choices. get the best small diaphram condenser you can. knowing your budget would help.
e604s for toms for sure and maybe a pair of studio projects b1s or the new audio technica 2020s or 2021s(the small diaphram cheapies they just came out with). depending on mic pres and the converters you have im sure you can get good sound from those mics. all of these will be in your price range.
