i'm looking to get back into biking after taking a break over the winter. i found an lbs with an '06 zebrano for $299 which is the most i want to spend on a bike right now. so i go there asking to check it out and thw woman said the frame was too small (15 inch) for me (i'm 5'6") and wouldn't sell me one because it wasn't the right size. this morning i went to another lbs and tried out the tiburon which was also a 15 inch frame, which was what the guy recommended for me, only it was $329. should i go back to the first lbs and get the zebrano?
