Another option is if you have a Bike co-op in your area they may have used mountain triples that you could get for less than ebay.... also I just put a FSA Vero 50/34 crank on my 89 Allez to get better hill gears. And I was able to get it for about $50. Not biopace but it will be hill Friendly also depending on your # of speeds (6 7 8) and gear type (cassette or Freewheel. You might be able to find a gear cluster with 30 tooth big ring set of gears. You can go to Velo base or Disraeli gears to find out the max teeth your particular rear derailleur can handle and if you really want to geek out check the Sheldon Brown gear calculator low gears are your friend
