though the original poster said he already had enough "projects".
I have built the MKARS80 and have the CW Adaptor Kit but have
not yet built the CW adaptor.NOTE: I *highly* recommend that if you go with the MKARS80 & CW Adaptor
that you add the Varactor with the 10 Turn Pot Tuning Mod.
(You can find it
on the Net, this mod is identical to the BITX20A Varactor & 10 Turn Pot Tuning Mod
This is an inexpensive, SIMPLE, no brainer mod that will immensly improve tuning abilities, especially for CW.
This is a really fun to build, high quality parts, great assembly instructions,
well performing inexpensive QRP kit rig.
Sure, 80m QRP, CW or SSB is a challenge!
But the challenge is doubly rewarded when you make the QSO
with a rig you built yourself....IMHO.
That's what I like about QRP......building my own rigs
and the resulting very rewarding QSO's.
Whatever way you go.....Good Luck and HAVE FUN!

PS: Another poster mentioned the Elecraft K1.
Can't get much better than that for a trail CW QRP rig,
though you are spending more money and effort (to build it,
but tat's 3/4 of the fun!)
