thorens or Rega

THe RB 250 seems to be getting better reviews then the RB 300, especially after having it modified, I'm still trying to find an RB 250 that has been modified? the dealer I'm working with says the RB 300 bearings are better and unfortunitly he is the only Hi Fi dealer in this area and I'm thinking he feels the RB 300 is worth the X-tra $100, I'm thinking finding an RB 250 and having the modes done will result in better sound? Reply with any thoughts you might have? Sorry this post sounds redundint,
Thanks,
Rick

Thanks guys for all your help.... I took some measurements with the Linn Basik arm that's mounted to the Rega 2 and found that from center of spindle to center of Pivot is 21.5 mm and from pivot to headshell tip is 23mm am I going to be able to use a Rega arm with the cut out that's already been made? I saw on the Origin Live site that I could get a RB 250 with the mods I want for about 357 us bucks is it worth putting that much more into it? I've got about 600 records and far prefer them to Cd's so I'm hooked on Vinyl, The cartridge is a Blue Point Special with low hours.....

Caterham1700, I've been thinking the same about the Linn Arm not being geo-metricly accurate and that what I need to do is get an RB250 with the improved wiring, then having that put in place on the Rega 2, to be honest I paid very little for the Rega and should have looked into that combination before I paid for this combination. Meanwhile I am going to go for the THorens with the BPS which I again paid very little for.....Had a R2 years ago with which ever arm came standard and a Signet cartridge sold that combo now wsihing I never had...can anyone help me get an RB250 with the new wiring? or point me in that direction? Thanks,in Advance
