I'd be tempted. If my CPE2 dies, I probably WILL buy one.
I can get 4x5 E6 done locally in Atlanta - for something like $3 a sheet I believe. Forget that, at least for doing very much of it. I send my 35mm and 120 to Dwayne's but will probably stop that. I just lack time to do it myself. But I'm trying to change that. Since I have the CPE2 I don't really NEED the new machine (though Expert drums would be nice) but could definitely see springing for it, after the new view camera I've promised myself anyway.
