no paypal for now.
a check is just as secure as a credit card--keep your stub and as long as it's not made out to 'cash' the only ones who can cash it are the ones that it is made out to. since every check that gets cashed gets a photo copy of both the front & the back, it's extremely unlikely anyone could cash your check & make off with the $$. even if by some .00001 chance someone did...you can't get charged for it if the casher's sigs don't match up and the correct bank wasn't used.
besides, ecelica is very reputable..i've never heard of anyone having a problem with the store other than the occasional complaint because a product was on backorder. if you're worried about someone taking your check in-route to ecelica..don't. the same rules apply as i already stated above.
