I've found MONEYTHING better than SAVINSTREAM customer service wise and they offer different types of security ...SS just do property
Do you follow this website? I find it a useful source of info and the companies post there too.

Which rival? I use Moneything/Savingstream and Collateral for secured lending and Ratesetter/Zopa as a variation ...my ISA is geared towards bonds at the moment with some stocks for a bit of spice...premium bonds for my 'ready' cash
