I'm not entirely sure what I'll go with as far as a replacement. I wouldn't mind staying with 6 speed though.
Looking at Amazon (I usually get an Amazon gift card for Christmas) I found a few nice options though:
Shimano MF-TZ20 for $11:

Falcon HG (possibly the same as what I have?) for $11:

Sunrace freewheel for $13:

And a shiny Sunrace for $11:

As you can see, I'm sticking with 14-28T, as that's what's on there now. I'm leaning towards the Shimano for the known tooling and quality. What do you guys think?
Getting the old freewheel off won't be a problem though. I had it off when I picked the bike up a month or two ago to service the hubs and all.
