Hello and welcome to the forum Sasquatch. Glad to have you here!
I would recommend skipping the mech mod for now. With a mech comes $40 in batteries & charger plus a new topper (rebuildable) in addition to the mod. Clearomizers can be run on a mech but you are limited to 4.2volts (decreasing as you use your battery). Then there is all the education on battery safety, ohm's law, amp draw, etc. if you go the rebuildable route.
Consider instead a variable v/w mod. The MVP v2 is extremely popular
1. Huge (2600 mah) battery
2. Variable Voltage - Voltage can be adjusted from 3.3 ~ 5.0 in 0.1 volt increments
3. Variable Wattage - Wattage can be adjusted from 6.0 ~ 11.0 in 0.5 watt increments
4. Ohms Meter - Reads the resistance of your atomizer
5. Pass through ability
6. $40 shipped at many online stores
The new iStickby eLeaf is gaining in popularity as well.
1. 2200mAh internal Li-Ion Battery
2. Variable Wattage (VW) up to 20W and Variable Voltage (VV) from 3v – 5.5v
3. 10-sec Protection: Maximum of 10 seconds per drag.
4. Atomizer Short-Circuit Protection: If atomizer short-circuits, the OLED screen show “Atomizer Short”.
5. Low-Voltage Protection: Once the battery is below 3.3V the OLED screen will show “Lock”, which means its time to recharge.
6. Unlock the Low-voltage Protection: The iStick begins working again once it reaches 3.65V.
7. Low power Alert: If the battery’s power is lower than 10%, the power symbol on the screen will flash.
8. Atomizers from 1ohm to 3ohm capable
9. Pass-Thru vaping while charging
10. ~ $50.00
