Rega P1 with RB100 tonarm? Of course I've seen it, but wow that may become a budget component of the year!!!! In that sub $400 category, we've only had maybe 2 to choose from. LP playback must be coming back.
Superpanama70mm is right though. Analog setup do cost alot. This is sort of a niche market, but selections are huge. I love having the options of changing sound.
Most of the free pre-mounted cartridge will get you spinning happily until you have more budget to get a different cart.
