I like Surly bikes, too. They're all steel bikes made extra tough, so always a good value. Chose carefully, though, according to your intended use. If you plan to ride mostly pavement and gravel for day rides, I'd stay with their lighter built models. I had an ECR and traded it off. Great bike, but not a good match for my riding. I'm a single day, out and back rider, on our paved and gravel roads. The ECR is a heavy built bike, designed to carry a full load of camping gear and a week's worth of supplies to remote places. Without a load, it's very stiff riding bike and way, way heavier than I need, and so a real tank to pedal. I'm not a weight weenie, but the bike was as heavy as some of my fat bikes. Make no mistake, a heavy bike and, especially, bigger heavier tires, are more work to pedal. I've pedaled a heavy fat bike on 30 miles on pavement, mostly to see what it was like. No problem for the bike, but I've done 60 mile trips on a road bike that didn't fatigue me as much.

Loved the idea of a bike that can carry me into the wilderness and back with everything but the kitchen sink and I still love the idea, but, hey, I'm just riding around the local roads, never more than 20 miles or so from home, carrying nothing more than the basics. My road riding is 90% pavement and the rest gravel, most of which can be handled with a drop bar 700x35 gravel bike. My current single speeds that I use for road rides all weigh 23 pounds and the widest tire is a standard 2.25" MTB tire, setup tubeless. Riding those really makes it hard to drag out a fat bike or even an ECR weighing a full 10 pounds more. Again, I'm not a fanatic on weight, but if you plan to ride out there on pavement or gravel and put in a lot of miles, think about how much bike you want to pedal. It's important.
