Would you be more likely to buy new gear out of state if there was no sales tax

AFAIK charging tax on goods bought in another state is against federal law.  States charge instead the same tax naming it differently.  For instance my state, Illinois, charges "Use Tax" which is tax for using goods bought out of state.  Since I don't want to investigate what was bought with or without tax - I elected option to pay flat fee proportional to income.  This option can be selected only if there was no big items bought without a tax.  Out of State tax can be very messy.  Some stores charge tax for items sold to another state illegally, because they have to be authorized, by the other state to collect this tax.

Enforcing that law would be like getting blood out of a stone!

Texas already collects taxes  on online purchases in some cases.  I think they struck a deal with Amazon and I don't know who else to charge sales tax.  I believe they can do this since the distribution centers are in-state.

Lobbyists for retail corporations have argued in Congress for imposing interstate sales taxes on internet purchases as a way to force internet shoppers back into stores--they claim this unfair advantage is reducing corporate profits--even though they have also lobbied for and have successfully rigged the tax code to pay almost nothing in federal taxes.  Don't feel as if you are cheating anyone--it is mainstreet America that continues to be oppressed and cheated.  You deserve a tax break, as well.   

Texas has a tax on breathing, double for minorities
