Upgrade Rega P3 or go higher end?

I have a Rega P3 purchased new from Lyric HiFi about 10 years ago, with a Blue Point Special Evo3 cartridge. Works fine and has no mods. But I'd like to improve my vinyl experience. I could easily add $5-6-700 worth of mods to the P3, but is it worth it? I really like the VPI Scout 1.1, in fact Lyric the salesman told me to buy the VPI instead of the Rega. Theres's a couple others at this price point that might be better than a modded Rega as well I think.
So is the Rega worth the upgrades and will it ever approach the sonics of the VPI (or that class of TT), or is it better to trade in the Rega and go for the more costly table to begin with? Thanks.
