I gig my EB180-12 quite regularly. Admittedly I do have a MAG210 hooked up to it, but haven't had to crank it past 4 on the volume so far. It's nice and punchy and I think it sounds great, I generally have the EQ totally flat with the Jazz or with a slight 220Hz + 1.6Khz boost with my Stingray.
I have a little experience with Laney amps (used them at practise and as a borrowed rig). I find them to be a bit muddy sounding, but that could have been just lack of familiarity with the EQ settings.
By the way you can get the EB180-12 cheaper here:

Here it is in action last week:
