I owned the Elys, which is the next step up from the Bias, and found it rather dry and dull. I think most people tend to be disappointed in Rega cartridges with the exception of the Exact, which is around $700 now. Also, bear in mind that Rega cartridges do not have user replaceable styli. When the stylus goes, you need to send it out to be professionally re-tipped or exchange it for a new one. If you're new to analog, and not yet comfortable mounting and aligning a phono cartridge, this could be a big negative.
The OM20 is a nice cartridge but it is basically discontinued. The OMN series dates back to the early 1980s and was really designed for the low mass arms of that era. The 2M Red is a more advanced overall design that is a far better match with the Rega arm. The Rega Fono should work fine with it. I guess you might say that the OM20 is more 'listenable' but it leaves me wanting more.
If you find a dealer that sells both Rega and Ortofon, you might be able to negotiate a slight package discount -- maybe 10% -- by buying both at the same time, and as a bonus, they will mount the cartridge for you. I would try Bess at Music Direct, if he's still there, assuming you don't have a dealer in your area.
When the 2M Red stylus wears out, you can always upgrade to the Blue stylus unit as it is interchangeable. You may not want to.
