I bought my ptw with a rebate "free money" i had it made to my ideal spec and it set me back around 2k.
I've had it for 6 years and it's the only gat ive had thats not needed any money spending on it. You could argue thats because i spent it all initially but it's really my most faithful performer.
The trigger response on them was streets ahead of anything else on the market at the time which was my motivation. Plus they also seem to hold their value reasonably well.
I've owned the cheaper TW platforms since and sold them all on as they just don't cut it like a Systema.
Would i buy another one? Probably not, I've a hankering for a recoil given the hysteria anout their performance. (I'd still buy a systema TW5 tomorrow as thats one of a few i regret selling).
As you all say, it's horses for courses, but i would argue mine was worth it.
