That must have been Cactus V2 (their first trigger, I believe). These were pretty terrible just like many other early triggers in that price range at the time. Some DIY antenna mods made the V2 triggers usable apparently.
My first Cactus triggers were the V4. They had a rather limited range (~15m in my experience) but were rock solid in that range. The V5 had a 100m+ range and, again, were rock solid. The V6(II) use the same radio technology as the V5, so again, the performance is flawless.
These triggers are not only "better" than the shoddy V2, they leave nothing to be desired in terms of reliability.

Pocket Wizard triggers provide no advantage over Cactus triggers, on the contrary.
Cactus triggers allow remote power control, HSS, and with selected flashes even full P-TTL support. Pocket Wizard triggers do none of that and the Cactus triggers are more than fast enough to support the sync speed of Pentax DSLRs.
@_pauls: Pocket Wizard triggers were once the gold standard of the industry. However, they never offered something specific to Pentax and due to their high-end pricing and the rise of good to excellent quality third-party trigger alternatives, went into financial trouble in 2014.
You'll be fine with non-specific Pentax triggers but only if you do not need HSS (high-speed sync). If you want the latter, Cactus triggers are indeed your best choice. Acon also did some P-TTL triggers for Pentax (Acon R930) but their website no longer exists, so it seems that option has disappeared.
