Hiya,
Welcome to the forum!
My first Scrapyard is gonna be the Yardkeeper too. However, it makes a lot more sense to grab something from the shop as you will get a far better deal than on the used market.
Get the DFLE now and hunt around for your YK later. I think those two would make an excellent pair that would take care of practically any cutting job on the planet!
I much prefer the LE versions myself. If I had the scratch I'd be all over the DFLE but da knife shopping is over this year for me (I only just squeezed the YK in). ; )
