For anyone interested I managed to do the following: UKash website converted to USD
£60 = $92.32

I used CashU.Com to add the USD Voucher to CashU my CashU Balance:
$84.14

I then used Add Funds from MtGox and selected OKPay to then use CashU as a funding source

An Hour later MtGox in my USD account has a balance of: $75.35

The entire process took about an hour, the longest part was waiting for the OKPay to deliver the money to MtGox.

If I were to buy at the current MtGox market order at $10.52 I would get 7.28 BTC

so in the end: £60 UKash = 7.28 BTC

so 1 BTC = £8.24 UKash GBP done this way The current MtGox Market Buy is £6.74 so £1.50 per BitCoin more, a full 20%

So For anyone interested in offers with 15% or less fees for a quick conversion the math is def there for that.
