There are other options in PCCs. Just wish the KelTec folks had addressed their ergonomic issues. To make it right, a lot of the MCarbo add-ons are either necessary or a good idea. This does cut into the current KelTec price, which has been all over the landscape. I'm embarrassed about what I paid for my second one, because they were made of unobtanium.
It all comes down to a size/price/utility analysis. If all you want is a really compact carbine, for occasional use, then they make a certain kind of sense.
