I find myself in a very similar situation. Im big on the glass tanks aswell. I have tried many different tanks and have spent a good amount of $$$ trying to figure out ,What I like best. Now I haven't tried the Aspire. But I think it may be something I would be interested in . I can't wait to get the Pro Tank 3. I know we all have our own desires when it comes to vaping Accessories and Tanks. If I find I like / love it. Then Ill buy a few more. If I don't like it .I have a few friends I can pass it down too.
Also Vendor shopping is a great hobby,. I have different sites where some protanks are $21 and the same tank at a different site is $10 and yes from reputable verified vendors. Happy Vaping
