Hi Chewy, I have watched, and enjoyed, many of the Moster Quest episodes.
There is a little bit of frustation feeling in that they can't seem to find any conclusive evidence, however they always seem to be able to produce a show that is entertaining, regardless of how flimsy the evidence may be.
Monster Quest isn't the first cryptozoological show however.
The first time I ever heard of "Bigfoot" was in the late 1970s or early 1980s, when Leonard Nimoy's "In search of" was aired on on Aussie TV just after I got home from primary school! (I originally saw it on a black in white tv... you can actually watch it in colour on YouTube).
There have been many other shows with a cryptozoological, or simply "unexplained mystery" focus over the years. In the early 1980s was sci fi author, Arthur C Clarke's "Mysterious World" (again viewable on Youtube).
This was lampooned in an episode of "The Goodies", where Arthur C Clarke actually turned out to be none other than Graeme Garden, and the Goodies travelled to the US in search of Bigfoot... At their destination, one of the Goodies, (I think it was Tim) got bitten on the toe by a mosquito, causing his right foot to swell to gi-normous proportions, causing him to leave gigantic footprints around the cabin when he went outside to go to the loo at night.
In the mid to late 1990s there was "Animal X" which seems to have been posted on Youtube by the copyright holders, (Storyteller Media) so I hope I have no copyright troubles posting the links here. Part 2 includes an interview with Senator Bill O'Chee (refer report posted on this site).

Another more recent show is called "Destination Truth", it is hosted by Josh Gates, and among other things, it investigates some of the lesser known cryptozoological creatures (many of which I have never even heard of!). I had the pleasure last night of watching an entertaining episode about the Mamlambo and the Tokeloshe in South Africa.
There seems to be a sense of fun, humour and camaradarie with the presenter and his team, which to me, makes Destination Truth all the more entertaining.
Anyway, if you enjoy shows like Monster Quest, I hope I have been able to provide you with a few more to look at that will give you both education and entertainment value.
. I've both seasons of this show and am starting on season 3. I find some interesting and a lot frustrating. I JUST WISH THEY WOULD FIND SOMETHING!!
AAAAAARWOOOOOOOOO!!!!!! ... cheers... Stickyfingers. 
I found myself running towards the light, “I’m coming sweet warm light, I’m coming” tears of excitement started running down my face, the anticipation of being chewy again was most pleasing.
