wow i hate time out. i had a large and informative post worked up but i'll hit the finer points real fast since i dont want to type anymore, lol.
510's : rock, have good vapor and battery life, can indeed burn a bit, flavor wise, still ok for fruit if you dont mind that, i dont.
401: better for fruit, has many devotees, great all around unit, slimmer than the 510
both great units, both fine for dripping. dripping rocks, i do it all the time. they have drip tips for the 510, check them out. tip style is a preference thing, i dig flat style.
e-......? no...just no.
only order china direct if you are becoming a supplier, otherwise, stay stateside, or uk at the furthest. fast shipping, better english. customs is the least of your worries there. they take shipment on occasion though
menthol is available in every concivable mixture, and bunches of suppliers on this forum are willing to custom mix, i just did an order with viking vapor, they do it, as does vapor bomb and i think dat vaper also. look around lots of amazing people in our supplier's list with great juice who can make it anyway you want, menthol and all.
litecigusa.net is a good supplier of nice kits. inexpensive, well made, good feed back. they came recommended to me, highly. i was impressed with my order, and their site has feed back. that said, again there are a ton of good folks to offer you a wide variety of products for great prices in the suppliers list. stay with forum suppliers, generally. they care about the community, are held accountable, should anything go wrong, so they take that seriously, and mostly, because they have good stuff, good prices, and a good attitude, generally speaking.
i like fruit flavors too, and im a big burly guy. rock on, and welcome aboard!
edit** keep spares of batteries and attys, as well as
e-liquid and maybe a charger, this will help you get off the analogs
