To waltz, yes we are both dealing with the same scott_lee from Ebay. Speaking of which, were you the one who outbid me on that first auction at the last minute? I'm almost positive my unit is a Mk2a...all signs point to this fact now. David from Empeg emailed me and told me if it was originally purchased from Sonicblue then it will be a Rio Mk2a. Honestly, I'm happy just being able to get my hands on one, but I do like receiving the same item I assumed I was bidding on. waltz, keep us posted when you receive your unit as to what size drive yours is...mine won't be here until next week sometime but I will let everyone know since interest seems to be running high!
