A HX stomp can be had for £400 used, less if you get a bargain. That won't buy you many single pedals these days, especially when you'll also need a board, some patch cables, a power supply...
Edit - Stuck in a boring work meeting ("no updates from me thanks") and got to thinking. My small analogue board is a PT Nano and a Cioks Adam, with a Korg Pitchblack, Darkglass VMT and Tech 21 Paradriver. Thomann tells me that's £715 these days, not including the velcro or the patch cables, and admittedly with the current smallest Cioks unit which does look a little better than the Adam. The HX Stomp is £545. It would be cheaper and smaller for me to buy the Stomp, superglue the 3 switches to tuner, overdrive and amp emulation, and never use any of the other blocks. Madness.
