Recently acquired a couple of Super Soaker XP 35s. While second-hand and definitely well-used, these blasters were remarkably in decent working condition and still perform quite well considering being more than 10 years old now. Size-wise, the XP 35 is definitely smaller than an XP 70, but roughly similarly sized to an XP 40. Size-to-power ratio feels good on this older blaster, still having a solid 1x stream output. Reservoir isn't huge, but isn't bad, either. Interestingly, on a full charge, one can more-or-less completely empty the reservoir without repumping and without too much loss of power (assuming that you only filled the reservoir ~70%, of course). Overall, rather impressive for a pistol-class pressurized reservoir blaster.
Full review to come eventually, but enjoy stats and pics for now.
