Is this a Back Up Cartridge or an Infill Period Cartridge.
How many hours is the Cart' expected to have usage as a weekly period?
Back Up, for me is a Substitute Cart' possibly to be used to preserve the longevity of another Cart' as an attractive End Sound option, which a reasonable sum might be considered to be spent to acquire a particular Voicing for a Cart' from a Brand that has attraction.
Infill, for me is a make do Cart' whilst something else is in waiting, like your own situation or a host of others that has similar influence on how a TT is to being used. A Cart' is not thought of as needing to be satisfying all wants for an End Sound, and does not need to be an excess cost, as it seen as a Temporary Measure.
Infill, as the wanted option, broadens the field of considerations and does allow Curve Ball suggestions to be made, as the New Experience that can be had for producing an End Sound might be an impact on oneself not thought possible for the good impression made.
Not too long ago, I was blown away by a Ceramic Cart' in use, and had to buy into the Model to always have the option at hand.
