I have a really, really inexpensive aluminum tripod (Ambico, I think is the brand). Probably cost less than $20 new. Very light weight and have never wanted anything "better". Perfect for my Rolleiflex. I also use it for my Hasselblad - but at shutter speeds slower than 1/125 I have to put the mirror up and open the back curtain before firing the shutter, otherwise the vibration blurs the image - I would think this a problem with other tripods as well.
In my experience, you can get 99% of the functionality you want with this type of tripod... and spend the significant savings on film or whatever.
And, as mentioned by Jeff, get quick release plates. Especially the one made by Rollei for your Rolleidlex - as the back can be damaged when screwed directly into the tripod. Also, it is just way more easy.
