I just bought a Cribber (well Nov but seems like yesterday!!), I bought him because of his temprement and genuiness, if you are happy to deal with the vice then go for it. My boy mainly does it in the stable after feeds. Quite a few top comp horses crib/windsuck - it's a behaviour which helps them deal with stressful situations. My boy does not loose weight due to cribbing. One other thing is if you keep yours on a yard then you will have to discuss the vice with the YO - luckliy it was mine who pointed me towards my boy as she worked with plenty of cribbers in her event groom career!
I have to admit the cribbing can grate on me sometimes but I deal with it - he tends to do it as I turn away from him so he turned it into a game more than anything.
Good luck with whatever you decide. I did post on here before I bought my boy and got quite a lot of info back which pointed more in the positive than negatives of buying a cribber.
Athena is a cribber and windsucker and these are the only vices she has. She is fantastic and wouldn't be without her. I just tend to let her get on with it.
I bought my TB ex racer windsucker last August, first horse, didnt really now what I was getting myself into. It really bothered me to start with but I love him to death so I have to put up with it. Again he tends to do it more after eating. It is also a game for him as well, as soon as back is turnes and all that!!
I have found running electric cord across top fence rail in field helps during turn out. Nothing works in stable, cribbox is rubbish. My only worry is his teeth wearing down, he is only 6 and they are already worn a fair bit.
I really wouldn't let it stop you buying the "one". I wouldn't change my little monkey for anything. Good luck
I bought my cribber not knowing he was a cribber (he'd always lived out before we bought him, and only does it when he's eaten - possible the previous owners didn't know either). It annoyed me to start with but now I just ignore it and consider myself lucky it's the only real problem he's got he doesn't do it constantly, either, which is good.
