What are you trying to accomplish?

If just switching to brifters I'd consider buying cheap 10s Campy brifters, a new 8s chain, a suitable front derailleur, an 8s Shimano cassette, and run a Shimergo "7 of 8" setup. Should cost less than $200.

Your hubs are 126mm 7s, so unless you replace the rear wheel (or maybe just replace the freehub body and re-dish -- most around here seem to think it's OK to wedge a new 130mm hub in a 126mm frame), you're limited to 7 of 8, 8 of 9, etc. Once you get a new wheel, you're edging close to buying a new bike from bikesdirect etc .
