No, you wouldn't regret it, in fact it is a very good deal!

I have several UniKlamps and many more K-Body's. The UniKlamps hold their
own for the less heavy clamping tasks, but you can still apply a fair bit of
pressure using the UniKlamps too. They are a great cost-effective clamping
solution for lots of woodworking tasks. Go for it!
