Yeah, Tapco catches a lot of (sometimes well-earned) flak for their products, but their AK line is actually pretty decent. The mags don't look very good, but you know, they work. I even like their Mini-14 mags for the same reason, they work. You shouldn't discount them straight out of hand.
Military surplus is always the best when it comes to 5.45 mags. It's a game of rarity at this point though. The most common thing you'll find right now are the surplus Bulgarian Circle-10 or Circle-21 mags. They used to be dirt cheap but seem to pull in $30-$40 a throw now.
Magpul is rumored to be doing a 5.45 magazine next year now that their feet are wet in the AK mag world. I'd expect those, if they do release some, to work pretty well like their other mags.
CDNN has a "commercial" Bulgarian 30-round magazine that is known to be bad. They're cheap, and there's a reason for it. Promags are also hit or miss, mostly miss.
All that said, your info there says NY so should we take the bandsaw to them and shorten them down a bit?
I think I have a Romanian 5 or 10 rounder that came with my SAR-2 in the AWB years.
