in the past i've used the Boehringer Mannheim Genius kit with excellent
results.  if you happen to have a freezer program and you factor in the
cost of radioactive waste disposal (no to mention peace of mind), the cost
factor is more or less a push.  people in my old lab have used the Tropix
Southern Light kit with very nice (but expensive) results.  however, Paul
Hengen recently posted his experience with an undocumented change in the
kit that makes it not work so well.  (by undocumented i mean that they
don't say anything about it in the protocol and call it exactly the same
thing, but if you call and ask they'll tell you that something is
different from the first round of kits)

good luck,
