Oh I know about stockpiling, I bought Babylon 5 on sale and it took me about 2 years to get around to watching it! If I were you I would take a Stargate break with another series and then do Atlantis which is only 5 seasons.
And only 2.5 of them are watchable!
Stargate after season 6 lost focus and got worse every season. Atlantis becomes very much like seasons 9 and 10 of SG1. In other words cheesy and over the top, but at the same time they try to be serious, so its really just ridiculous.
Season 1 is really good, and half of season 4 (the one after SG-1 ended) is fun. It's decent, i miss cheesy sci-fi on TV, but it's not the same tone as Stargate season 2.
