4.5 firmware doesn't increase the price but it may increase customers.
["4.5 does not increase the price]yes it does increase the price it cost way more to get one on ebay and people buy them all day long though if your patient like i was i got a used xl with 4.3 on ebay for 99 bucks
I would take ebay prices with a pinch of salt -- it costs not a lot to keep the listing going/relist and you always have the chance that someone with more money than sense will come along and snap it up.
As ever something is only worth what someone else is willing to pay for it.
