Yes, I recommend NEW_LIFE_ELECTRONICS. Bought a lot of stuff from them and never had any problems. They currently have several lots of MR16 and PAR30 bulbs that have been going for cheap.
The Sylvania 78748 bulb is, by far, the best PAR20 out there. They are 3.5” long. I did have one (of 20) fail after a year. The dealer replaced it immediately.
