That kit is a basic Shurflo pump kit, there are several manufactures that build the same basic setup. You can also source your own parts and build your own.
The cheaper Shurflo pumps may not have the right seals to handle high concentrations of methanol. I had to relace my demand switch on my shurflo when it corroded due to methanol leaking past the original seals. Shurflo company was very helpful I simply called them and explained my issue and they sent me both a replacement switch and replacement seals that were more suitable for high concentrations of Methanol.
That price strikes me as almost too good, I suspect it has one of the cheaper pumps in it, or the web page is old and has not been updated recently.
I have not heard of that particular vendor before so cannot say what sort of support you might get from them.
There are several high profile companys that sell very similar systems and have good reputations.
I home built one and buying the shurflo pump on the web at the best price I could find. I paid almost the same for the pump alone a couple years ago for what it is worth.
The last price I saw for the true high pressure pump all by itself was $140 - $185 depending on where you buy it.
There are several versions of the sureflo pump that differ in max pressure, motor power rating and seal materials to name a few differences.
Spend some time shopping around and touch base with several of them and make sure you are getting what you think you are getting.
Here is the manufactures listings on the pumps, you might want to inquire what model number that pump is.

The design on those pumps produces significant pressure spikes so the pump rated by the manufacture to be a 60 psi pump can actually run up in the 100 psi range but is not really designed for continuous operation at the pressure level. The true high pressure pumps will draw about 11 - 12 amps at 120+ psi, so you might want to ask them about current draw if they are reluctant to tell you what pump model it is.
You really don't want your pump to fail when your under load.
