Can recommend SGS Engineering for their boot strut regassing (if you find that the boot doesn't open to full reach by itself, then this could be useful for you).
For £40 they will regas and send both struts back to you. This works out as about the same cost as replacement struts from SGS, but the replacement ones aren't OEM (and why replace something when you can refurbish the original).
If you are regassing your struts, make sure that you don't take the metal end clips of the end fittings when removing the struts. You just want to slightly loosen the clip, not remove it all together (otherwise it is difficult to get back into place).
