Learsfool,
I wasn't arguing the judgement of whether it's worth the extra money or not, just that it's a closer call than you are portraying IMO. It appears from your last post that you still may not understand the pricing. Again, the price of the P7 (current list - $2695) includes a dedicated external power supply that is more finely tuned than that available to the P3/24 and P5 (current list w/TT PSU - $1770). So the differential is actually $925 total, still a lot, just not as much as you were saying.
