I am looking to return to vinyl and am thinking I should upgrade my BP25 with a phono stage and I am also thinking of purchasing a Rega P3-24 TT.. I would love to purchase a BP26 but I cannot afford it at this time. Would it be worth my while to get the mc version or do you think the mm version would be the best bang for my buck? Any advice is appreciated. 
My current system consists of 4bst, Rega Planet cd player and NHT 2.9 speakers.

Hi Steve
To be cost effective the MM will be fine as there are a lot of cartridges available, I've had good results with the Sumiko Blue Point I & II MC, Dynavector 20x also come highly recommended as another high output MC, although you'll have to advance the volume control a bit more with both of these. The MC stage is one of the best but the cost is a lot more as well as the cartridges.
The Regas are basically plug and play, so if you do not want to fiddle too much they may be the way to go, but there are a lot of good turntables out there.
I would not loose sleep over getting the BP26 which may have a slightly lower noise floor than the BP25 but probably lost with vinyl, I'd stick with what you've got and get the MM phono board.
