actually, someone else made this mistake recently. the 15$ line item is a soldapullt REBUILD kit, not a full soldapullt unit. However, I do have two more blue complete krytox-powered DS017GH soldapullts for 20$/ea. from there on, every soldapullt with be a black krytox-powered DS017LSGH. the pricing from the blue units won't change much (a couple dollars more than the non-clearance DS017GH price of 30$, that's about it).
i've definitely desoldered some pretty crazy stuff (8ga stranded wire? yep!) with DS017 models. and yes, i also have an 808. the thing about the 808 that's great is that you can completely desolder a through-hole board in minutes. the not so great thing is that you can't desolder SMT pads. it will pull the pads off. the other nasty thing about it is that you can completely clog the nozzle/tip, especially when desoldering lead-free joints, and a new tip is like 15$. it's possible to do even worse too. let a post-filter sit for too long in the unit and you will destroy the vacuum pump. it's powerful, but naturally is fussier than a plastic pump.
what i like about the soldapullt most is that it's always ready to pull solder off of anything. no heatup time. no plugging things in or finding the power switch (i've hacked a power switch onto mine and actually upgraded it to an 80w element, and i'm still to impatient to use it most of hte time). the soldapullt is also exceptionally durable. you can pull SO MUCH CRAP into a soldapullt before it even starts complaining, and then you basically just dump it out, wipe the o-ring down, run some water through it and it'll do another thousand joints.
