I have had great experiences with them as well. I used to use Eurotubes, but tubestores prices are on par with any US site, and the shipping is quicker/cheaper. They are quick to answer any questions and give advice too.
+1 The tube store is excellent! They are located in Hamilton On. shipping costs are low prices are much better than stores, John at the tube store is very helpful in choosing the right preamp and or power tubes for your application. Check it out.
