The cheapest one is probably the Uni-T 71A, Franky.
It sells for about USD90.00, plus postage (Chinese sellers on eBay)
You can probably get it for slightly less, directly from China.
It is very good value for money, if one can get past the weak input protection.
Its real CAT rating is probably closer to CAT II 250V only.
