i've got a tesla and its great, nice spread with good long distance throw as well. Doesnt have as many fancy features as the wilma like the remote switch and programmable power modes etc but its nice and simple which is what i wanted. Wilmas are good too but tesla seemed better value (i paid £218 last year)
I think i'd get a tesla over a wilma again if i had to choose.
Only thing is… theres a Deal extreme light (DX light i think) which is basically a tesla copy for £50, although not sure about long term durability. Might be worth looking at.
Where are you if you're near me (lakes) can have a look and a demo of mine.
WIlmas are upgradeable, tresla isnt, but dont think i'd be bothered about upgrading anyway as i have enough light with the tesla, and also lupine upgrades (for the wilma) are still £££
