The sale is inevitable. Newegg.ca always runs sales, periodically (I would say at least once per quarter). Rarely, however, do the 200 and 202 go on sale simultaneously. But eventually the 202 will go on sale (in the past it's sometimes gone on sale a few days after the sale on the 200 ends).
Then get the 200. I like having the second port for faxing. But if you don't need the second port, don't waste money.Based on your previous post, the features on the 202 won't help me much. I don't need the router, don't see how I would use the second phone port and the last one was the OBiPlus (not available anyways).
Btw, the OBi100 is discontinued: http://blog.obihai.com/feeds/posts/default
