If your not getting the LE, then whats the rush to get the pro or premium? Go and play one and decide if you really want it. I would think a year from now you will still be able to buy both of those models new.
If your not sure, I would go and buy a STTNG instead with your $4k. A year from now, you can sell or trade it and you will know all you need to know about the stern.
dylan, nice to hear your getting one. I got my LE on tuesday(2nd NIB pin), but its going to be sitting in its box for a while as I am swamped with work right now.
