looking at snorkels on Ebay (as one does) this morning and wondering about the differences in prices, as one could guess who could tell by the pictures as to what you may or may not get but I did notice one thing and wondered if it makes any difference. the less expensive snorkels seem to have a two piece design where the inlet goes into the fender and the more expensive ones seem to be one piece. does anyone have any incite on this and whether it would make any difference at all?
