I've been watching this product and it has always been around £104 for the ready to run version. Price varies by under £1 due to USD exchange rate. Occasionally some items go on sale but that's clearly shown as a reduction in price.
The price of this and most stuff varies on a day to day basis at HobbyKing,It could be 100 quid on Tuesday, Then find its 50 quid on Wednesday for no real reason other than some algorithms going on somewhere.
You may drink your weak lemon drink now, or save it for later.
Reviews seem to be ok for it but guess driving it full speed in to a wall, as one reviewer did, isn't the brightest thing to do. :/ Other HK stuff has been OK but agree it's not Traxxas etc quality so check all screws tight, gear mesh OK etc before first run.
