Casseroll would jump to mind but it might be more than you want to spend. I was shopping for something similar recently, though I didn't have a preference for calipers vs cantis. The casseroll I ruled out due to price . It's not expensive, but I was on a big budget. I looked at the Pake. It's a good deal. Kind of a poor man's crosscheck. A little less tire clearance and a little heavier but otherwise similar. I also looked at Bikeisland. The Jury might work for you, but there's a good chance your calipers are too short. It takes EXTRA long brakes. Kind of an odd looking design but otherwise nice frame. Then there's the fantom cross uno which I almost bought but couldn't get over the Moto logos (I know, vain).

I ended up building a used Bianchi Volpe which has short horizontal dropouts. I really like it. Stable and comfy but doesn't handle like a boat like some touring frames. The dropouts are on the short side so depending on your gear ratio you might have to use a half link. 39 x 15 pouts me almost at the very front but no slippage so far. Cool. The San Jose is the same frame but with 120mm track ends. Also there's the On One Pompino if you can find it.

What spacing do you need or want? That narrows the options a bit.
