If you want a clear one you could do what I did and just buy some 3mm perspex (acrylic) and make it yourself. It cost me £10 for a 4ft by 2ft sheet, which will make at least 4 pickguards. I then drew around the original black pickguard, cut it out with a fine bladed jigsaw, filed and sanded the edges, put the old one back over the top to drill the holes (which I then countersunk), and all done. It took me about two and a half hours, and although it's not absolutely perfect it's very close (with a bit of practise I'm sure you could make it perfect). The only thing to be really careful of is drilling the screw hole close to the point, as it can split the perspex.
