Repaint the Enduro like I did, then when you snap the chainstay (again) the replacement won't match!
Spesh will warranty the chainstay (there is another thread on here about the same thing) as it's a (very) common problem (I broke four and on the fourth instance I also noticed a small crack in the main frame so Spesh gave me a brand new 2010 Enduro frame).
After that I replaced the bike with a Nicolai Helius AM, which was about as close to my Enduro as I could find in terms of numbers but a little lighter.
Nomad is no were near 4-5lbs lighter; that must just be down to the overall build. The frame is about 1.5lbs lighter than the Enduro.
I don't think the Alpine 160 is a good replacement if you're a fan of the Horst Link; having ridden one you do notice the lack of performance on steep terrain when you need to drag your back brake to control your speed. It's not a problem for everyone but I didn't like it much.
Other bikes that would be a good replacement would be the Chumba and the current Enduro model.
