NHS is hardly an unknown....Been in business since 1987 and judging from their website they can do everything TPS did at least as good if not better! With their trial period and the notation of how well PXYN liked doing business with them, I certainly think that they are a reputable company...and even a poster called and TPS spoke highly of NHS shows that there is a good relationship probably between all three parties, just that PXYN is trying to get better terms with TPS before going nationwide with sales!!! Makes great sense to me!
