I've been in a gigging band in the past but backline was always provided so never had any need for a really good amp. Best one I've had was my AVT150 which I really loved, especially when I added a 1922 cab but it never got any use so up until today I was just using a Marshall MG15 and practicing/jamming directly into my computer using my old Line 6 Toneport.
Anyway, we are looking at getting an extension built so my one stipulation to the wife is that I can pick up a guitar and have an amp ready to go at any time in the extension so...I needed a nice amp, right?!
I've always planned on getting a nice Marshall but a few years ago I saw the Blackstar stuff in magazines and it was always getting great reviews despite the competitive price. I was looking at adding an HT-Dual pedal to my little Marshall MG15 just to get a little flavour of the valve tones but they cost from £90 - £180... Then I saw this HT20 on my local Gumtree for £290 ono. I paid £250 for it. 
Only had it half an hour, and I've got housework to do and need to work on my new book (I've written a couple of historical fiction novels, Wolf's Head and The Wolf & The Raven) so I might not get get much time to play with the amp today. Had a quick play along to Tull's "Farm on the Freeway" with my PRS SE Custom 24 and I love it so far!
Anyway.....hi from Scotland!
