I'm looking for a recumbent. I ordered a can of Finish Line Dry Lube from Nashbar. They sent me a Vittoria 20" X 1 1/8th - 1 1/4" inner tube. They made it good - but told me to keep the inner tube.
Test ride as many bicycles as are available to you. Try to come down to two you like best. Sleep on it. If you are about to buy one, but you keep feeling that the other one is what you like best for whatever reason - even the color - get that one and ride, baby ride!
