Hi GtheMISFIT and welcome !
Spend an evening looking through the list of 'forum suppliers' (at the top, up there ^), on a price-checking hunt for 510 atomizers - specifically, 510 "bridgeless atomizers". You'll find them, and you'll get a real quick education on what is available, and competitive pricing.
I'm looking at one forum supplier vendor's page right now and the price is under $4 for 510 "bridgeless," atomizer, and under two dollars for a 'shorty' 510 cartomizer, (shorties are a great way to enjoy a bit more of a taste of a flavor that you know you won't vape all day). You can order half a dozen for about the price of one tank. You'll need a 'drip tip' to fit on the top of the atomizer, usually about a dollar or two, depending on plastic, aluminum, etc - (but you change that out so you really only need one....or two, or three

.
BC and TC clearomizers can be had all day long for under $6 that will also work well with the Itaze for tasting. The plastic in Polycarbonate clearomizer
tanks can react with certain eliquids (citrus/malic acid/cinnamon, etc) so if you're going to keep an
eliquid in the tank for any length of time, then go for glass. I have a few models of 'slim' tanks on my Itazte such as the protank2v2mini and the aerotank mini that keep the straight-line look of the Itaze and can be found on sale at under $10-15 dollars.
If the eliquids pass the 510 test, they get to go in a tank and visit 6 to 8 watts.
Good luck!
