Have rode two of them now and was close to making the move this year if it wasn't for our brutal dollar and the price of the kits. That is after 20 years of riding sleds in the mountains.
Both i rode were 4 strokes (YZF-450 and 450-XC) and i used to race a 450 SXF in supermoto. My current ride is a Husky TE300 two stroke though which is due to the low maintenance and light weight. You are exactly right that the oil needs done after every weekend of riding, valve checks every 20 hours at most and when you go to rebuild it is very pricey. A two stroke leaves out the valve maintenance, still needs tranny oil changed (not as often as a 4 stroke needs engine oil) and will still require looking at after a season however a top end for a two stroke is very cheap in comparison to a 4 stroke and can be done by anyone with a little bit of mechanical prowess, personally i wouldn't even know where to start with a 4 stroke. Same can be said for items like exhaust (2 stroke $350 for a full exhaust vs 4 stroke at $1000+) or head (2 stroke $200 vs $$$$$$$$ for a 4 stroke).
If i was building a snow bike i would start with my 300 and put on an APT Smart Carb to eliminate jetting constantly. Would then do a high compression head ($200), FMF Fatty exhaust and shorty silencer ($350), and bolt up parts like larger pegs, seat, hand warmers and large hand guards.
Also, when picking a bike i wouldn't even entertain using one that doesn't have E-Start. I stalled the YZF in a really bad spot on a tough sidehill and had a hell of a time getting it kicked over again.
If you do go that route look at the Lectron carbs as well. APT pissed me off for a year with their promises of delivering a product and it never happened so I went with Lectron on my KTM which was also cheaper and its been flawless.
As for the two stroke comments, if you haven't ridden a two stroke snow bike but like riding two stroke bikes you should try one. I tried a 250 KTM 2 stroke last year with some motor work and a SmartCarb and it ripped. It responded very well and the 250's like to be on the pipe a little more than the 300's and a little feathering of the clutch really made me like the 2 stroke over the big thumpers.
As mentioned the newer 4 strokes have he conveniences of fuel injection, a little more torque and many have the easy button but used KTM 2 strokes with estart are easy to find for less of an initial investment over the newer 4 strokes. Of the people I now with 4 strokes only the guy bouncing them off the limiter all day are doing more valve work but overall aren't seeing big issues, and with the gear reduction of the track kits there isn't a bunch of added strain on the gear boxes to really add more fluid changes.
I am not sure I would make one my full time winter ride but it does open of a tighter terrain and its a lot of fun!
