Just to confuse the issue - check out the thermarest neo air. I've used quite a few different mats and now that the neo has come along, I think I have found my final mat. I have previously used a Kathmandu mat (it pains me to write that), thermarest prolite 4, Pacific outdoors 4.5cm thick mat, exped 7 and now the neo - lighter and much easier to inflate than the exped and more comfortable than the others.
If you still want to go with the prolite or prolite plus then go prolite if your hips don't get sore and you don't feel the cold plus don't plan on camping in freezing conditions, it is after all lighter. However, the prolite plus is noticeably more comfortable and necessary if camping below about 10degrees - that is my opinion on the temp. not thermerests. Don't get too concerned about the pricing, buy what you think is most suitable for you.
Cheers,
