Let me counter the points that you made, if I may?
A basic Provari (mod only) is $159, not $200. Many customers already have a charger and the batteries needed, so a kit is not always necessary.
Provape outsources the colored bodies to another company to apply the karocote paint finish, and this costs Provape $20 for this service. Provari charges only those customers the extra $20 to those who desire a colored Provari. This keeps the cost of a basic Provari reasonably affordable to those who are on a tight budget, instead of charging $179 for EVERY Provari. Do you really expect Provape to eat the cost of the paint service?
Provape has to spend $15 additional to their supplier for the blue and green LED displays. Again, this additional cost is passed on only to the customer who wants those colors.
The $25 charge for the battery extension cap is pretty much standard for add-on attachments. AltSmoke charges $25 for their Kick extension sleeve for their Silver Bullet; I don't hear of people complaining about that.
The vast majority of people who have purchased a Provari have no interest in variable wattage. It's just another method to get to the same place. People who own a Provari have bought one because of its reputation for being more dependable, reliable, consistant, durable, and actually being repairable for as long as you own it. Do you really want to get into the repairability of the Chinese mods after warranty? "We build cheap. You buy cheap. It break, you buy another."
In life, you often get exactly what you pay for. Construction workers and mechanics who depend on tools for their trade, don't buy cheap tools. They buy name brand, more expensive, higher quality tools that will take a beating and last years, not weeks or months. The Provari could very well fit in this category if it was a tool.
If you don't mind buying a 2.0 Provari (brand new, same electronics, full warranty), you can often find one in the Provape clearance section for $150. Slightly blemished 2.5 Provari's same price. If you like pink, there's a 2.0 Provari in clearance right now for $135. So there are deals available if you are on a tight budget and desire a Provari.
