First season into cycling and have logged about 2000 miles since April, but will have to think about riding indoors a lot this winter and am about to purchase a trainer. Looking for advice on what to look for: durability, resistance levels, rim-drive, etc. $399.00 seems to offer a lot of features, but there are a lot of $150.00 models out there also. What are the better brands / models out there. Not looking to spend $1,000.00. What do you think??
