>Struggling whether I should get the wash and cure 2 in 1 or just DIY my own?
A ready-made system (well-designed) makes things fast, easy, and convenient. A DIY solution depends on your relevant skills. Is it possible to make something comparable for cheaper? Of course, otherwise the manufacturer wouldn't make a profit from it. You can go simpler too, of course. Rather than a timed powered alcohol stirrer, you could shake parts in a colander in a plastic tub. This would probably require more alcohol and space unless you can size the parts just right.

>Washing seems easy but not sure about curing
Optimal curing for most resins involves 405nm light at about 10W/cm^2 intensity (specifically, not higher, per Formlabs tests IIRC), usually with elevated temperatures (depending on resin). This wouldn't be very hard to DIY, though the timing, turntable, and often heating on purchased models can be nice. Most standard UV LEDS are a suitable frequency.

Whichever you decide, some tips:
Use two different batches of alcohol for washing: a first pass that picks up most of the resin (this gets dirty fast), and a second pass that removes lingering residue. Two fast washes like this cleans better (and the alcohol is usable longer) than using a single batch of dirty alcohol. Excessive time in alcohol can weaken the print, so watch this.
Photo-hardening resins are thermoset resins. They harden in response to heat as well as light, hence the common use of heat during curing. A very effective method of curing is to immerse a print in hot water in a clear container in a curing station. This method is recommended by Siraya Tech for their engineering resins, and specifics will vary by resin. Immersing in hot water after UV curing also works.
