The H801 comes with firmware that is closed source and Chinese written so I inherently don't trust it... Reprogramming it just means it runs different (open source) software (I even partially wrote some of it), but still sends/receives messages with Hubitat via WiFi. This is an option with higher customisation, but more complexity as a result. There is a huge thread about it on the ST forums here and covers the flashing process - Or here for Hubitat setup
Roughly roughly:
2x 2m Philips Hue strip = £140
(RGBWW and likely easy setup - not sure if you would need a hub though)
OR
5m Warm/Cool/Daylight/... white LED strip (link above) = £25
2x 12v 60W power supplies = £18
2x H801 controllers = £14
1x FTDI to reprogram the H801 = £2
(this would just be a single colour white, and more DIYing, but might be fun and would be a nice LED colour, less than half the price)
Or some IKEA Trdifi (or something like that) strips - would work out somewhere in the middle pricewise (probably still a single colour, slightly less customisable but easier setup than with H801s)
