To answer your question on two parts: as for downtime, i suppose it is partly to do with the service provider…and if that service provider is anything like TalkTalk….they could be down more times than they are online…talktalk being crap providers [ speaking from bitter experience]
with respect to the price io their ( Fleetscale or any other provodors] product:….
put it into perspectibve…how much does a pint of beer, a shot of whiskey or a glass of wine cost these days..and how long does THAT pleasure last, compared to building a model.
Paying £700 for a semi kit has to be laid out into the many hours of pleasure that it itself can give to a modeller……………..and then the cost doesnt seam too much………….perhaps a thousand hours building equates to 60p per hour where as a scotch at £3.00 a shot lasts just 15 minutes if you are lucky ( so that is £12.00 per hour for your enjoyment).
By that reckoning, a model at 60p per hour is mighty good value indeed, and you have something to show for it at the end of the day, not just a cricked neck looking down at the urinal basin, lol
