ODK Moderator bonnar_bloke is sure to chime in, when he sees this topic, and can certainly give you the best local advice on SB45's and repairers.
A word of warning though, the repair cost will depend on just which bits need replacing. If only the bedknife is damaged, that's not too bad; but if the cast iron soleplate and/or reel need replacing, it will get exy.
