Huggy-
I looked at using the VA to pay my DPE fee, and it was going to burn 2-3 months of benefits, just for the $650. vs 6 months of benefits for a $7k+ payout if I used it for a 737 type.
IMHO, it's probably not worth using for just the DPE fee, unless say you have just a couple months of benefits left and want to burn them.
Personally, I plan on doing my 737 type + ATP-MEL checkride when I get back from OCONUS, and then when I get to the next "School Year" doing my CFI/CFII/MEI at a local 141 school in the Hampton Roads area, trying to get the max bang for the buck. I have serious doubts about any future offspring (none currently, at least that I'm aware of)actually being able to use my GI Bill, because I feel that's one of the next things to be axed when money is tight.
