Phono preamp selection has a lot to do with your equipment. It's important to match a cartridge that is suited to the compliance of your tonearm as a first step to achieving good sound quality. Beyond that is the choice of using a moving magnet (higher output) or moving coil (lower output) cartridge. There are also moving iron carts from Sound Smith.
So there are lots of variables to consider.
Since you are planning eventually upgrade your turntable, I suggest reading up on turntable - cartridge - phono preamp combinations on several online sites. Vinyl Engines, Audio Asylum, etc. can provide you with some insights. You may want to look to local audio retailers who specialize in vinyl setups and do some listening.
In the interim, I would suggest looking at moderately priced phono preamps in the used market (Audiogon, U.S. Audio Mart, etc.) that will work well with your current phono cartridge (MM or MC). FWIW, I would suggest settling on your next step turntable and cartridge combination before buying a phono preamp. That way you won't be wasting your time or money.
There are a lot of great moderately priced phono preamps out there, especially on the used market. Here is a link to a thread which discusses several very good, moderately priced phono preamps on the Steve Hoffman forum:
