I would watch Isle, they have been having frequent sales over the past few months (it seems like they just had a board refresh and are probably trying to get rid of old stock). Their Pioneer board is currently $495, as of writing this and this seems like a good entry level price. It looks like you can get it through Amazon at that price point, but I don’t know if you will also receive the 2-year warranty from ISLE if you purchase through Amazon, so it maybe worth going directly through ISLE if you’re comfortable with it.
