I've been finishing out and restoring and repairing bamboo rods in the Edmonton area for the past 15 or so years. I offer restoration and repair of bamboo rods but can't post a link to my business website here so PM me if interested in viewing my work and learning more about bamboo rod building.
I have only ordered one blank from Angler's Roost in the past and it didn't stack up to blanks from reputable blank builders in the USA. I promptly sent it back for full refund.
Probably the best deal in a high quality blank is from Dennis Stone of Stone Rod Co. located in Oregon. He does great repair scarf work too should you ever break a rod section. He often offers blanks on sale in spring and fall for a decent discount. I've built out 3 or 4 of his rods to date and have been extremely happy. Rod blanks are in the $250 -$350 USD range depending on configuration and length (more rod sections = more $$$)
Another builder that offers very high quality blanks at decent price is Tim Zietak located in Pennsylvania. He offers many classic tapers in both hex and quad format. I've completed a couple of quad rods from him in the past and have plans for more. Rod blanks are in the $300-$400 USD range depending on configuration and length (more rod sections = more $$$).
Lastly I will mention Bill Critchfield based on decent quality work but more importantly his blanks are relatively inexpensive (not much more than Angler's Roost). He offers them on the big auction site and they go for $200 USD or less. He produces some great tapers, but to be honest the only reason I don't use his blanks is that he uses Titebond III adhesive to glue his blanks up and I feel that yields a slightly softer (slower) blank than would otherwise result if an epoxy or URAC adhesive is used.
There are other builders, but these are the ones that are reasonably inexpensive and have short turnaround time. And they all stand behind their work.
I source out and buy rod components from various suppliers mainly in the U.S. including Struble for cork grips and agate stripping guides, Bellinger for high quality reel seats, Snake Brand Guides for their high quality guides. I get my aluminum rod tubes from Landmark.
REC also carries a large selection of high quality reel seats and does sell cork grips, guides, rod tubes and other components too.
Companies like Angler's workshop and Golden Witch in the U.S. sell all the components and consumable supplies like adhesives and silk thread you'll need.
Rodbuilders Supplies is a Canadian company located in Victoria B.C. and does carry a good selection of components used for bamboo rods. I have used them in the past and Andy is a great guy to deal with.
Just thinking out loud here but another good option for you is to get a better quality used vintage rod and do a complete strip down refinish job. While that may or may not necessitate replacing a cork grip and reel seat, At least you will get experience wrapping all the guides and learning how to straighten rod sections and fit ferrules. Then you will also get a chance to varnish a full rod.
Anyway just food for thought. PM me or email
