@AlanKeni Have looked into X-max fog ? Airflow is a bit tight,but ok for direct inhalation. If you are into factory made vapes.. it is one of the best i've tried from China.
Constrution is aluminium,there is a silicon seal with ceramic screen followed by metal one. It does an awesome job when paired with a WT and has replaceable batteries,i suggest you look into the dedicated thread,also there are some pretty sweet deals bout it going on for at the moment i think.
If you really want something handcrafted and portable. TUBO and Splinters (Vapefiend.com for EU) are really nice vapes. For portability i would choose either TUBOevic or a Splinter with a Box mod ,but for performance and pairing with water tools my heart goes to the TUBOx,a real powerhouse ... (I didnt do a good job with my recommendation i guess.. just checked and TUBOs are now over 200$(was 175 when i first got ,but TUBOx + mod can still land at that mark)..
If you looking for a desktop, i suggest taking a look at Logvapes,they stood the test of time and deliver really thick hits,you can set it and forget.. The MUSA is over you price range,but you can take a loot at it since it is manufactured in europe..
Since you already own a portable that you are happy with ,probably it is best to look into desktops too.
https://underdogvapes.com/ (oops just checked and they are left puppies out of your price range only),,
If you decide to go for Logvapes i recommend the Underdogs ,mainly because i have had them, always been happy with them and also The Creator is an urgent need of help ,if you wanna help your Karma ,it is the best choice around ! Anyway if you dont dig those take a look at the Hi or E-nano( which also might end up over 200$ with the taxes and shipping though.)
Another good idea is to post an ADD in the classifieds that you are looking for one .I bet you can snatch a sweet deal from out beloved members ,as i did many times already.
