>>1044606>Any reason not to buy the Surly Disc Trucker for a tour? Seems decent to me and the bike looks pretty nice.From what I hear it's a great choice for a tour, but not so much commuting. Rides like a boat
If it's a real, loaded tour, you aren't going to do much better on a new frame. Fuji Touring is probably a better deal but I expect less attention to detail there.
Here is a real long list of stuff out of your price range. Best to learn
