Only managed 2 blasters I've liked, and one of those has gone now, too:
Fire/Fire, 36. Only blaster set I've ever really loved. I'm happy to suicide myself on her, and debt doesn't phase me. Throwing fire about is just too much fun.
Elec/Elec, 28, Deleted. Back before defiance 2.0, it was painfully boring with the mezzing to death. Might try it again.
AR/Dev, 11, deleted. Too boring.
Energy/Energy, 5, deleted. Rooting annoyed me. As did the mismatched power colors.
AR/Dev (only thing on my US account from way back when)
Energy/Energy - re-made from an Energy/Elec because... I can't remember...
Sonic/Elec
Sonic/Mental

Carlsberg don't do Farming,
But if they did..........
Ice/Devices/Fire (50) - Incredibly fun to play, dropped all /devices powers that would slow my pace down. Really nice and fast to play these days. Still the character I play the most.
AR/Ice/Force (47) - Polar opposite of the previous - Slow and steady. Ice Patch + Ignite is really nice a combo.
Elec/Fire/Cold (41) - AoE monster. Backed up by a personal Empath. Can keep AVs taunted pretty reliably as long as the team is lacking in the Gauntlet department.
Psi/Energy (6) - Just started this little bugger. Seems nice.
And of course there are a few ones I've deleted along the way.
Fire/Fire - My very first character. Debtcapped from level 5, but got destroyed when CoH went live.
Ice/Energy - For the S4 PvP tournament. Deleted to make room for other things.
And others I can't remember just now. (couple of Archery/s, at least one Sonic/, perhaps another Fire/ or two...)

Clearly I only do straight forward concepts. 
He will honor his words; he will definitely carry out his actions. What he promises he will fulfill. He does not care about his bodily self, putting his life and death aside to come forward for another's troubled besiegement. He does not boast about his ability, or shamelessly extol his own virtues. - Sima Qian.
Elec/Elec 50 - My first ever CoH character. Still play him on teams occasionally as he does decent AoE damage

Archery/Energy - L50
Ice/Ice - L20
I recently deleted an Energy/Energy and an Elec/Elec at low level to make a Sonic/Energy and a Psychic/Mental, but I can't really declare them until I get them to L20+ (which is when my characters usually reach safety from deletion).
Blaster is the only non-Epic hero AT that I enjoy as much as the villain ATs, so doubtless I'd be playing my blasters if I wasn't so wrapped up atm with getting my stalker to 50 and playing all my new spiders/widows/doms/brute/corruptor.
nrg/nrg - SL39
elec/fire - SL29
ice/fire SL9
fire/ice SL8
can't decide between the last to....

They were appropriately appalled
at the discovery of the eight victims
They're now putting it all together.

with one leg missing
Eight legs, one body, silk,

Okay first of all i have to admit if people ask me about the only AT i can't play in CoH, answer is a blaster. I see people having so much fun while playing one blasters are too chaotic for my taste.
Also as blasters are most popular AT and many people ask about rarest one here's our chance to point a place for them.
Only ones i can declare are:
Sonic/Elec (lvl 20 deleted)
Ice/Mental (lvl 16 and lvl 14 deleted)
