Based on the respones, it looks like almost any of the 0w20 options would be great. My only concern was I read that the Toyota (and possibly Honda?) variants are a bit thinner at startup than M1 and PP, but I'm not sure if that truly makes a real world difference.
The current Honda Ultimate has very similar viscosity properties to M1 AFE and the current Idemitsu 0w20 available from Subaru. I used the Honda/P66 oil in my Civic and it did well. Search my username for the UOA. I've also used the old high-moly, 200 VI Idemitsu oil and M1 AFE in my Civic. Currently on M1 AFE.
As others have said K-series engines aren't generally that picky about oil, so go with whatever 0w20 is most available and lowest cost, they're all pretty good. If you want the Honda oil but don't want to pay $9/qt for it, buy Kendall GT-1, it's the commercial equivalent. "Petroleum Service Company" has good prices and will ship nationwide.
As to TGMO being thinnest at startup, that depends on the startup temp. M1 AFE has superior MRV viscosity, but that only applies to temperatures below -10*C. The higher VI of TGMO only really helps a bit with fuel economy any way.
