It is impossible to say how much money you need to spend to get something 'good'...looking at the specs for that preamp, I see a S/N ratio of 80dB, which is better than some units that cost 3 times as much, and that is one of the more important things to look for. Plus, it is designed by the same company that made the cartridge you are using, so they likely used them together when they were designing it. For what you want to do, it will get the job done!
