Not really anymore for the ones with built-in batteries like the disposables. Similar to disposibles they are typical 20W or less. You can get many of them for under $30, including the UWELL Caliburn line which is a quality product line. The G Coil packs are between $10 and $20 depending and last a week or more per coil of which there are 5. If you chain them, you're probably looking at between 2 and 3 days per coil.

The mods that require rechargeables like 18650 and other similar form factors sit between $50 and $70 for reputable brands, though for the ~200W mods it can be around $100 if you include their branded tanks.

I'd bet your mod is at least a 100W+, probably over 150W depending on when you bought them (they are cheaper now than a few years, which were cheaper than a 10 years before that).

The tanks are pretty cheap now too, even those multi-coil rebuildables. If you don't rebuild your tank and use pre-built coils it is going to be a little more expensive. Those tanks for pre-builts tend to be a bit cheaper as well, like ~$30 for non-pods. Pod tanks tend to be around $10 - $15.

I remember 80W mods going for between $100 and $300 back in 2011 depending if it was considered a "clone" or not.
