We have a few Multitracks around here because I’m pretty sold on their usefulness and quality. We have a 730 and 720 from China and a 730 made in the US. The US 730 is a nicer bike than the Chinese one. If you’re looking to upgrade from your 700, I’d look for a US 730 or 750. I’m not convinced anything less would make the upgrade worthwhile. I don’t have the model years in front of me, but you can look them up in the old catalogs.
