On the Juniper side, the SRX220 is VERY tempting at 8x GigE interfaces and 950Mbps (claimed) thruput.
I recently asked for quote between SRX 210, 220, and 240. The price difference between 220 and 240 are not much, however 240 is much more powerful. I would not recommend anyone to use 220 model since people should jump to 240 when 210 model is insufficient unless Juniper can lower the price
