I was one of those that was hesitant about even getting a subscription, but after I did, I was pleasantly surprised with the amount and variety of items available that Poserworld is always the first place I check when I'm looking for an item. When you join, you automatically get the DVD with the older items (which are not in runtime folders, and, yes, sometimes have some bad code or missing textures, etc. But they were created back when Poser was new software and the advancements were limited). 

I heartily recommend whatever you can afford. The $20 for 1 month is still going on, so try it out. And yes, A3/H3 don't have as much, but what they do have cannot usually be found anywhere else. And that is the beauty of Poserworld -- to find that which no other store offers.

Poserworld is a valuable resource for me, and I have not regretted my yearly subscriptions. I would go lifetime if I could afford the amount, but I have limited funds.
