You're looking at spending about £1,000 + (+ VAT)
look on ellisons and beauty express.. search for autoclave. These two models we used at college.
Glass bead sterilisers or u.v. cabinets are not worth using as bead sterilisers do not reach all the surface areas of tools and uv cabinets, well as soon as you remove the items they are not in a sterile environment and it all depends on the uv output of the bulbs and this will diminish over time plus the hassle of using tissues to turn your tools over every 15 minutes each side. You will still have to wash / cleanse your tools with antibacterial detergent before you use the autoclave and rinse out and replace the distilled water each time you use it ! my lecturer who also worked from home used barbicide.
Personally I use mundo
The only time you really need an autoclave is when invasive procedures are done such as microblading and epilation, SPMU etc.
Hope this helps with your decision but I see I was beaten to the post
