Which Rowing Machine?

Hi folks. I was hoping for a bit of advice. I’m looking into buying a rowing machine to use at home. At the gym I invariably find myself using the concept 2 rowers as opposed to any other form of cardio equipment, so I thought it might not be a bad idea to have one in the garage for the days when I am just too busy to make it to the gym. Sadly, they are becoming more and more frequent. The rower that I use at the gym is a Concept 2, a heavy duty bit of kit with a price tag to match. Unfortunately, I am going to have to settle for something a little less expensive. Which will obviously mean compromising on quality and robustness. I was wondering if anybody could recommend a good make or model that offers a nice balance between quality and price. I’ve been having a look at rowing machines for sale online but there is that much to choose from that it is difficult to make a decision. I’d much rather make one based on somebody else's recommendation. Any pointers will be much appreciated folks.
