The best prices I've found are at ACF Greenhouses (the automatic one partway down the page, turquoise in color) and Farmtek, but are those good quality (as in, will they last atleast a few years)? Has anyone ordered either of those and if so how are they holding up?

Is there a better type out there than the ones those companies carry? Any of them prone to shorting out and shocking you? (I'll have it plugged into a GFCI power strip, but I don't like to trust those things completely.)

And the two companies above ~ do they have good customer service if someone has a problem? How is their shipping ~ quick as they say it is and well packed? Do you know of a better company that's easier/better to deal with? I'm very willing to pay a couple extra bucks to buy from a good company.

Thanks in advance everybody.

Thanks also, GringoJay, for the info on Christmas lights. I'd thought about using those, but don't have many extras ~ certainly not enough to do the area I need to cover. I'd also read about rope lights done that way, but the cost would be about the same once you buy all the fittings to hook them up to a plug-in setup and factor in the pita-ness of having to do that. And having splices in electrical wires in a greenhouse does give me pause... Might try it still, but will get my electrician friend's help to do the splicing.

If anyone else has anything to add, please do!
