As has been stated, Kitchen pipes are generally marketed as a practice instrument. They're ok for what they are, but a decent set of small pipes is infinitely better. I bought a set of "kitchen" type pipes sold under the Bagpipes Galore brand from Edinburgh. A bit finicky on the tuning, but a serviceable practice instrument. I have a set of Walsh A2000 mouth blown smallpipes and a set of Gibson Firesides in A. Of those two, I prefer the Walsh. I also have a Fagerstrom Technopipe(s?). That's also a very handy practice instrument. It doesn't replace the regular practice chanter, since it doesn't involve breathing. Used with the earbuds, or a small battery powered speaker, it's great for practicing. I put mine in my lunch can, and practice during lunch at work, or during any down time we get. Plugged into a good quality amp, it sounds pretty impressive. Being somewhat of a technological Luddite, I haven't figured out that midi business yet. My understanding is it's to pipe the signal directly into a computer or music mixing device. Way beyond my comprehension.
There are a couple other electronic chanter type instruments, Deger, and Ross, but I have no experience with them. There is also a full electronic bagpipe, the "Redpipe". Comes in different configurations, many of which look like a traditional bagpipe. Again, no experience with these other than what I've read on the internet. I understand they're used by some rock bands, and it seems they're quite expensive.
