Prismall, 22, was traded to Windy Hill by Geelong late last year after requesting a move from of its talent-laden list.
Essendon coach Matthew Knights was prepared to offer Prismall a fresh start, even though a knee injury sustained in the Cats' qualifying final win over St Kilda meant the midfielder would not play until midway through 2009.
"It is humbling that they did try and get me, despite the knee," Prismall told afl.com.au at the Bombers' Telstra AFL Community Camp in Melton.
"It's part of football now that blokes change clubs and chase opportunity, and I'm really happy that Essendon and Geelong could work something out.
"The move has been great. I can't speak highly enough of the club and the players and how they've received me.
"They've made me feel like one of their own. I can't ask for more than that.
"I'm just really looking forward to getting out there and training with them, and hopefully playing sooner rather than later."
Prismall said the surgeon's most recent assessment of his reconstructed knee was positive, but didn't indicate when he'll be able to play.
"From the start we said anywhere between round six and 10 is pretty realistic," he said.
"I'm still on track for that but there is also the chance it could be earlier or could be later.
"I've never been through this before and everyone who has a reco reacts differently at different stages of the rehab.
"I'm more than happy to play when it's ready, if that's round 14 or round four."
Prismall, who has played 25 matches, remains haunted of the moment his knee buckled underneath him at the MCG in September.
"I think about it pretty much every day. It's hard to escape it," he said.
"I get asked a lot about how it is, and I'm always doing things to try and better the strength in my leg.
"It was just one of those things that was unlucky but, at the same time, I was really fortunate to play in a really strong side and then to get the opportunity to come to such a fantastic club like Essendon."
Prismall has finally relocated to Melbourne after commuting from Geelong for the first month of his new contract. His partner is now teaching in Port Melbourne.
"We're living in Newport now, so it takes me about 15 minutes to get to the club," he said.
"It's way better than the hour it was taking me when I first came to the club."
