Well don't what your looking and pricing is different over there too.

I do know you will need at least 1.5 liter or larger tank and that tank dimensions is important too as want to be able to fit in your carbs. I used a Kendall unit which was very the similar one that Harbor Freight sales. You will at least 60 watts transducer and heating would nice addition. You might say I fought with mine for two years in one sense. The timer was limited to 8 minutes cycles which made doing multiple cycles necessary. I was only able to clean small two cycle carburetors (chainsaws and string trimmers) and some larger mower engine carbs with limitations. It served its design purpose well but my needs quickly out grew it. I actually sold it to purchase my 6 liter replacement.

Currently I using a 180 watt (3 transducers) commercial model with a 6 liter tank 200 watt heater and a 99 minute timer. And believe it or not it looks like I might out grow it too as I take on larger equipment.

Your cleaning solutions will depend on what your cleaning and not all commercial cleaning solutions will not work equally well. This is something that fellow forums members should be able help with as they will know what is available in your area. I usually fall back to my Dawn Ultra dish soap here for cleaning as I can change out the solution more often as it gets dirty without great expense.
