Budmaster (pricey) worth a mention,of course they're expensive but I am loving my GOD 190w panel in combination with 2 citizen COB 50w each, Best results I've ever had and a joy to work with in regards to heat,saving a third on electricity, I did buy it because I was frightened of my DIY electrics as I've had a fire before and uk don't have a huge selection Like USA and the cost of shipping a cheaper alternative from USA costs nearly as much as the Budmaster and returning if problems can prove costly, I am going to tackle a small DIY build next now I know how easy it is and use it for a small 80cm tent compare results.
