As a person particularly interested in land values in SL, I watch the trends on the secondary market. For those who don't understand the term, this is a market where people who own sims sell them, full transfer, to new estate owners. Linden labs charges 1000 USD for a new full prim sim, and with that sale, the purchaser gets one month with no tier payments. So the actual value of the new sim from linden labs is $705, with tier at $295 beginning a month after purchase.
This week the secondary market for sims hit new lows. i've seen full prim sims selling for as little as $400 usd, with tier for several days already paid. The seller is also responsible for a $100 usd transfer fee.
I think you should consider these issues when you are voting on our land sales pricing policy.
